While I still don't have any documentation for the BCM5705, I recently obtained a Broadcom driver with 5705 support. After scrutinizing it carefully, it looks like the differences between it and its predecessors are: - No jumbo frame support - RX return ring is limited in size to 512 entries - No support for DMA'ed statistics block (stats must be read from registers instead) - Initialization of certain on-chip blocks and parameters are skipped - 5705 rev A0 has a bug that requires a workaround: the driver has to poll the NIC's memory after setting up the RX descriptor ring to verify the chip has actually loaded it. I have merged all these changes into a copy of the bge(4) driver from -current (should also work with 5.1-RELEASE). You can get it from: http://www.freebsd.org/~wpaul/Broadcom/5705 To use it, just drop the supplied if_bge.c and if_bgereg.h files into /sys/dev/bge and recompile your kernel and/or if_bge.ko module. Unfortunately, I don't have a machine with a 5705 chip in it, so I need other people to help me test these changes. If you have avilable right now: - a laptop or other box with a 5705 gigE chip - FreeBSD 5.1-RELEASE or -CURRENT - another network interface that you can use to load this driver Then please test this updated driver for me and report back. Information that I would like to see: - Describe the system with the 5705 chip in it (I'm under the impression the 5705 is being used in embedded configurations only) - A copy of dmesg output showing the ASIC revision of your chip (doesn't have to be a verbose boot, though I won't mind if it is) - A detailed description of any problems you may observe while testing the driver Information I don't want to see: - Requests for help with other totally unrelated drivers - Requests for help transfering large sums of money out of Nigeria - Information about septic tank clealing - Pictures of people getting it on with barnyard animals - Bikeshed arguments Thanks in advance for any help anyone is able to provide. -Bill -- ============================================================================= -Bill Paul (510) 749-2329 | Senior Engineer, Master of Unix-Fu wpaul@windriver.com | Wind River Systems ============================================================================= "If stupidity were a handicap, you'd have the best parking spot." =============================================================================
